3.7 Ribbon Tension Adjustments
When the ribbon slips or wrinkles during printing, adjust the ribbon tension. The printer has already been factory set with the ribbon width of 114 mm. When using ribbon with a different width, adjust it according to the following procedure:
a)Hold the ribbon roll with one hand so that it does not turn.
b)Slightly push the knob toward the ribbon roll with the other hand and rotate the knob until the stopper comes to the desired position.
c)Gradually release the knob so that the stopper fits in the groove on the knob.

d)After printing, check for ribbon wrinkle or slipping. If it occurs, adjust it further according to the following procedure:
(1)When the ribbon wrinkles, the tension on the ribbon winding section should be increased.
(2)When the ribbon slips, the tension on the ribbon feed section should be decreased. If the problem is not resolved even when the tension on the ribbon feed section is set to 3, the tension on the ribbon winding section should be increased.
If ribbon problems are not resolved, consult our service personnel.
